About

Sign any PDF in about 30 seconds, right on your iPhone or iPad. Import a contract, lease or form, tap the highlighted fields, add your signature and share the signed copy. No account, no uploads: every document stays on your device. FIELDS FOUND FOR YOU Plainsign reads the page and highlights every place to fill in: form fields, blank lines and empty check boxes, even on scanned paper. Tap "Next field" and work through the document in order. SIGN THE WAY YOU LIKE • Draw with your finger or Apple Pencil, with pressure-sensitive ink • Type your name in one of four handwriting styles • Use a photo of your signature on paper • Save your signature and initials for next time FILL IN EVERYTHING • Text, dates, check marks and initials anywhere on the page • My info: your name, email, phone and address in one tap • Initials on every page at once • Snapping and a magnifier for precise placement SCAN AND IMPORT • Scan paper documents with the camera, with edge detection • Import from Files, Photos, Mail or any app that shares a PDF • Unlock password-protected PDFs ORGANIZE PAGES Reorder, rotate, remove and extract pages, or merge documents into one. Save any document as a template to reuse it. SIGN IN PERSON Hand your device to someone else to sign. They see only that document and can change only what they add. When they are done, you confirm it is you to take it back. A RECORD OF EVERY SIGNING Add an optional certificate page with the document's fingerprint (SHA-256), who signed and when. PRIVATE BY DESIGN • Documents are processed on your device and never uploaded • No sign-up and no account • Optional Face ID or passcode lock • Works offline PLANS Your first document is free. To sign more, choose a plan: Weekly with a 3-day free trial, Yearly, or Lifetime as a one-time purchase. Every plan includes every feature, with no watermarks. Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage and cancel subscriptions in your App Store account settings. When a free trial is offered, any unused part of it ends when you buy a subscription. Plainsign makes simple electronic signatures. It does not provide qualified electronic signatures and is not legal advice.
